Why run Wehe?

Have you ever wondered if your ISP is slowing down certain traffic relative to others?
Unfortunately, you mobile device and carriers currently give you
little or no way to tell if this is the case. With Wehe,
we give you a way to test if this is happening to your traffic.

What does Wehe do?

Wehe uses your device to exchange traffic recorded from real, popular apps like
YouTube and Spotify---effectively making it look as if you are using those apps.
As a result, if an ISP tries to slow down an YouTube, our app would see the same behavior.
We then send the same app traffic, but replacing the content with randomized bytes
, which prevents the ISPs from classifying the traffic. Our hypothesis is that the randomized traffic
will not see application-specific shaping, but the original traffic will see it.
We repeat these tests several times to rule out noise from bad network conditions, and
tell you at the end whether your ISP is shaping your traffic.

For more details about our methodology, please check out our technical details page,
written both for non-technical and technical audiences.

How do I start?

Wehe currently works for both Android (4.4+) and iOS. It is beta software, so
there are some limitations and we appreciate your patience and help with fixing
them. To install:
